Ataxic Hemiparesis

An ataxic hemiparesis is the second most frequent type of lacunar syndrome, or a stroke emanating from the arteries that provide blood to the brain’s deep structure. The ataxic hemiparesis presents with a combination of neurological and motor symptoms and include weakness, clumsiness, and affects the leg more than it does the arm and can also be known as homolateral ataxia and crural paresis. The duration of these symptoms can last for hours to days.

Causes of an ataxic hemiparesis are often lesions that can produce both a weakness and ataxia, or lack of muscle coordination that can effect speech, vision, and movement. Not to be confused with Ataxic Cerebral Palsy, an ataxic hemiparesis can occur in anyone with or without the disorder. Most notably, Ataxic CP is caused by damage to the cerebellum area of the brain, while an ataxic hemiparesis is caused by damage to the corona radiate and the anterior limb of the internal capsule regions.
